After months of speculation, Meghan Markle and Prince Harry have confirmed they are expecting their first child.

A spokesperson for Kensington Palace announced that the Duchess of Sussex is due in Sping 2019.

But according to body language expert Judi James, it was totally "obvious" that Meghan is pregnant.

Here's why:

1. The outfits

"Meghan always seemed to prefer sleek styling but recently her clothes do seem to have skimmed over her stomach rather than fitting or clinging to it," Judi told the Mirror .

"The blue dress with what looked like a tummy bump might have been photographed at an odd angle but some subtly ruched dresses or the peplum she wore on the trip to Ireland provided stronger, subtler clues. The open lower buttons on her coat at the wedding nailed it though."

"Some of the biggest clues came during Doria's visit for the Grenfell event. Like many mothers whose daughters are newly pregnant with the first child Doria didn't leave Meghan's side, while Harry walked behind looking slightly over-awed and sheepish."

3. Harry touching her protectively

"It's usually Meghan performing the loving, quasi-maternal touches on her husband when they appear in public, especially the gently steering and reassuring back pats," she went on.

"Recently though it's been Harry placing his hand on his wife's back. Protective rituals like this are common during the start of a pregnancy when the man often wants to step up into caring mode."

4. Harry mirroring her gestures

"[At Princess Eugenie's wedding] Meghan stepped out of the car and walked along with one hand covering her stomach. This self-conscious cut-off covering gesture is very common during early pregnancy when it can feel as though all eyes are on what might not even be a bump yet.

"But then Harry mimicked the gesture as he walked along behind her. Subconscious mirroring of this gesture by the husband can be a give-away that both the man and the woman have one exciting secret on their mind."
